Abstract

Proposition of a Cellular Automata (CA) model of carbonitride precipitation to simulate image of microstructure in microalloyed niobium steels is presented in the paper. CA model proved to be very efficient in modeling various phenomena in material science. Numerical modeling played important role in development of new processing technologies taking advantage of precipitation. By modeling we mean a mathematical description of the relation between the main process variables and the resulting material properties, based on sound physical principles. In microalloyed steels the microalloying elements: Ti, Nb, V are added in order to control their microstructure and mechanical properties. High chemical affinity of these elements for interstitials (C, N) result in precipitation of binary compound, nitrides and carbides and products of their mutual solubility – carbonitrides. The model accounts for an increase of dislocation density due to plastic deformation and predicts kinetics of precipitation as well as shape of precipitates.
